You may need to use back-up birth control (such as a condom/diaphragm with spermicide) when you first start using this medicine, or if a patch has become loose or has been off for longer than 1 day. Read and carefully follow all instructions about what to do if a patch gets loose or falls off, or if you forget to change your patch on time.

If you need major surgery or will be on long-term bed rest, do not use wear a skin patch for at least 4 weeks ahead of time and 2 weeks afterward.
